Rapid Motion Estimation Algorithm for Embedded Video Monitor System
Peng Tie-gang · Jisuanji gongcheng · 2009
Motion estimation of time-consuming brings great difficulties to real-time video encoding. In order to improve monitoring of real-time video encoding,a rapid motion estimation algorithm for embedded video monitoring system is proposed. Based on the characteristics of a relatively fixed monitoring background,the algorithm uses multi-criteria of early stop,predicts search starting point through vector movement relatively characteristics of time and space,finally,uses improved rood search pattern starting search. Experiment shows that the algorithm has better search rate than adaptive rood search algorithm with slight PSNR decrease,matches the real-time priority principle in embedded video monitoring system.
